Stela of King Ka'a of black quartzite inscribed with the Horus name of the King. This stela is decorated with a serekh (a rectangle with paneled lower half) surmounted by an image of the falcon god Horus. The Horus-name was the oldest element of the pharaoh’s titulary and associated him with the falcon god. The two large pieces of this stela were discovered at Abydos during separate excavations of the Early Dynastic royal cemetery. The fragments were reunited at Penn Museum in 1903.
